The AD9260 is a 16-bit, high-speed oversampled analog-todigital converter (ADC) that offers exceptional dynamic range over a wide bandwidth. The AD9260 is manufactured on an advanced CMOS process. High dynamic range is achieved with an oversampling ratio of 8x through the use of a proprietar y technique that combines the advantages of sigma-delta and pipeline converter technologies. The AD9260 is a switchedcapacitor ADC with a nominal full-scale input range of 4 V. It offers a differential input with 60 dB of common-mode rejection of common-mode signals. The signal range of each differential input is 1 V centered on a 2.0 V common-mode level. The on-chip decimation filter is configured for maximum performance and flexibility. A series of three half-band FIR filter stages provide 8x decimation filtering with 85 dB of stopband attenuation and 0.004 dB of pass-band ripple. An onboard digital multiplexer allows the user to access data from the various stages of the decimation filter. The on-chip programmable reference and reference buffer amplifier are configured for maximum accuracy and flexibility. An external reference can also be chosen to suit the user's specific dc accuracy and drift requirements. The AD9260 operates on a single +5 V supply, typically consuming 585 mW of power. A power scaling circuit is provided allowing the AD9260 to operate at power consump-
